How does poultry feed production machine affect pellets size?
With the energetic advancement of contemporary aquaculture and also feed industry, the requirements for feed quality are getting greater and also higher. For pellet feed created by poultry feed production machine, pellet size is an extremely vital top quality evaluation index.


Neat and also constant pellet feed not only satisfies the sales requirements of feed producers, yet also fulfills the real breeding demands of users. Pellets that are as well long, also brief or unequal are not conducive to animal feeding. In real manufacturing, the size of the pellets generated by the poultry feed manufacturing machine is typically called for to be 2 to 3 times the diameter of the pellets.

For instance, granules with a size of 3 mm are normally produced with a size of 6 to 9 mm. Of course, according to real user requirements and also different feed selections, the length requirements are not always within this range.

Consequently, in order to create feed pellets that satisfy the demands or as close as feasible to the demands, we will certainly go over some aspects that influence the pellet size of the poultry feed pellet making machine and also find the matching control methods to make it beneficial to the production needs, which is necessary for feed suppliers importance. Based upon years of experience in poultry feed granulator design and also field debugging, we will discuss this issue from the adhering to facets.

1. Specifications impacting the poultry feed production machine itself:

The output of the poultry feed production machine is Q (kg/h), the internal size of the ring die is D (mm), the reliable size of the ring die is W (mm), the direct rate of the ring die is V (m/s), and also the rotational rate of the ring die is n (r/ min), the ring die aperture is d (mm), the ring die opening rate is m, the variety of openings is n (items), and also the granulation size is L (mm),.

For the above formula, it is not difficult to analyze the variables affecting the pellet length L of the poultry feed production machine:.

( 1) The influence of the result of the poultry feed manufacturing machine.

It can be seen from the formula that the pellet size L is proportional to the outcome Q. With various other criteria consistent, the greater the return, the longer the pellet, or else the shorter the pellet. Consequently, adjusting the outcome of the poultry feed pelletizer to fulfill particular pellet length needs is a possible option. In real feed manufacturing, feed producers do the very same, sometimes giving up big quantities of output to fulfill pellet length requirements. This concern will certainly be stated in the following discussion.

( 2) Influence of ring die line rate or rotational rate.

It can be seen from the formula that the pellet size L is inversely symmetrical to the ring die linear velocity V or the ring die straight speed n. When the feeding speed, that is, the output Q, stays continuous, the quicker the ring die speed, the much shorter the instantaneously extruded pellets, and also the other way around. For different dimensions of poultry feed pelletizers, the rotational rate of the ring die varies greatly.

Generally, the turning speed of the tiny poultry feed making machine is high, and also the rotating rate of the huge poultry feed production machine is reduced, but the straight rate of the ring die is controlled within a suitable range, normally between 6m/s ~ 9m/s, to meet the needs of granulation.


When pellet mill in Madagascar of the ring die is tiny, the high quality of the pellets is high, yet the pellets might be longer than required, as well as the line speed is also little, which will certainly impact the result; when the linear rate of the ring die is high, although it is beneficial to enhance the output, the pellets may be shorter than the demands, as well as the quality of the pellets It will certainly become worse, which calls for the feed producer to pick its own ring die line speed according to different feed selections, and realize it by transforming the transmission ratio of the poultry feed manufacturing machine transmission system.

( 3) Impact of ring die aperture and also porosity.

The ring die aperture D has no straight result on the pellet size L, it has an impact on the length L together with the variety of openings N, that is, the size of the ring die opening up proportion, since the opening proportion and also the square of the ring die size D as well as the number of openings N is proportional to the item of. The larger the porosity of the ring die, the much shorter the pellets, as well as the other way around, the longer the pellets. The aperture proportion of the ring die corresponds to various ring die apertures. For instance, a ring die has an opening price of regarding 25%, and also a ring die has an opening price of concerning 38%.

Usually speaking, the bigger the pore dimension, the higher the open porosity. In actual production, specifically when producing small-diameter pellets, such as 1.8 mm shrimp, some individuals grumble that the pellets are also long, which is triggered by the fairly low opening rate of the ring die when the aperture is little. Among the solutions is to sacrifice part of the return, or to achieve by boosting the line rate of the ring die. On top of that, adjusting the cutter is talked about listed below.

( 4) Influence of ring die inner diameter, reliable width as well as pellet thickness.

For the poultry feed manufacturing machine, the inner size D of the ring die and also the efficient width W of the ring die are taken care of criteria, which normally do not alter, and it is not easy for customers to transform them, so they will certainly not be gone over below. The pellet density is associated with the raw product for granulation as well as additionally to the compression proportion of the ring die.

The higher the compression proportion, the stronger and denser the pellets will be. Nevertheless, for basic products, the pellet thickness is not really various, so the pellet density is not the main influencing specification, so it will not be discussed too much here. In short, for the same granulation basic material, the bigger the pellet density, the shorter the pellet size.

2. Just how to solve the oil-free phenomenon in the manufacturing procedure of the poultry feed pellet making machine?

Poultry feed production machines are powered by electrical energy, yet oftentimes oil drive has ended up being vital. As most of us recognize, the devices works fast as well as depends totally on the power belt, as well as oil is particularly essential as the power supply of the equipment.

Resolve the problem of no oil in the poultry feed production machine:.

( 1) The manufacturer of the complete collection of equipment with an outcome of 5 lots of concentrate suggests that you check the main shaft and also rotor of the poultry feed pellet machine first to make certain that there is no material deposit in the gap.

( 2) The maker of the little poultry feed manufacturing machine advises that the customer requires to carefully clean the filter screen in the oil filter.

( 3) Get rid of the grease block of the poultry feed manufacturing machine. Usually, the device of choice is: an effective hollow tube of a specific size, primarily utilized to clean the contaminations packed into the oil hole.

( 4) We commonly claim that along with checking the above issues, we need to likewise check whether there is oil leakage at the refueling part. If the oil leak is specifically serious, it will most definitely bring about no oil supply. The service to this problem is to include an oil lining.
